  1. Diagonal

    A diagonal is a line joining two nonconsecutive vertices of a polygon or polyhedron. Informally, any sloping line is called diagonal. The word "diagonal" derives from the ancient Greek διαγώνιος diagonios, "from angle to angle"; it was used by both Strabo and Euclid to refer to a line connecting two vertices of a rhombus or cuboid, and later adopted into Latin as diagonus. In mathematics, in addition to its geometric meaning, a diagonal is also used in matrices to refer to a set of entries along a diagonal line.

  2. Hal Buell:

    Like any good, experienced and talented photographer, there's a sense of anticipation and a sense of shooting a picture at peak action -- and Joe got it, you couldn't have captured the action at a better peak. A moment earlier, and the flag would have been too low. If it had been a second later, the flag's staff would have been straight up and the photo wouldn't have had that strong diagonal line.

  3. Hal Buell:

    It's exquisite, you have this strong, diagonal line made by the flag staff. You have the flag snapping in the breeze. You have the pyramid-like shape of the Marines pushing the flag up. The men obviously are separate, but they appear as one. The blank background enhances the action by providing no distractions. Also, the photo is gifted with a softly filtered light. A very thin haze of clouds filters the light so that the shadows aren't harsh, but there is detail in all the shadows on the uniforms and the flag.
